Got hacked yesterday. The link came from inside Claude chat. I was installing a transcription app. Claude sent the download link, and I pasted the command into the terminal. It all looked legit. It wasn't though. It was a copycat site bundling malware. It ran instantly, tried to take everything from me. Nothing sensitive got out. So I wiped the laptop and rebuilt clean. But here's the scary part. Restoring from the backup, I found a poisoned SKILL.md for Claude Code. It looked exactly like my own writing style guide. But buried inside: it had instructions to silently re-download the malware and steal my credentials every time the AI loaded it. If I'd restored that one file, my new clean laptop is owned on day one. What saved me: I read every skill, hook, and config file before letting the AI touch them. Two lessons here: AI assistants will hand you links they never verified. Check before you paste. And AI agent files are executable code now, disguised as notes. You have to read them. Stay safe out there.

"The cybersecurity reality we live in now is teenagers are running around in organized crime gangs with digital bazooka’s. They probably have a better asset inventory of your network than you, and they don’t have to wait 4 weeks for 38 people to approve a change request for patching 1 thing." If you think that patching critical public facing infrastructure within 24hrs is not a realistic goal then tell me why! Despite all the security awareness we have here in 2023, all the new fancy tools we have, and all the celebration of coordinated government take downs of threat actor groups, cybercrime gangs are still on the rise hitting more companies and making more money than ever this year. You need to be able to identify and patch something like CitrixBleed within 24 hours — if you cannot, there is a very real possibility it isn’t the ideal product fit for your company due to the level of risk it poses, and you need to rethink if the architecture and look for a solution you can manage. The LockBit ransomware group has assembled a strike team to breach banks, law firms and governments and I don't see this stopping anytime soon.

12) Forgot to mention - it seems having initial Pfizer doses then switching to Moderna has slightly less severe headache, fatigue, nausea, and myalgia than a 3rd Pfizer dose. medrxiv.org/content/10.1101/…

BEST BOOSTER? Mix it up — but depends which you had first. Switching vaccine for the booster seems to be the best—Pfizer to Moderna booster, Moderna to Pfizer for booster, and J&J should switch to Moderna / Pfizer booster. HT to @ScientistSwanda. #COVID19 #BoosterShots #vaccinate

ah. This goes a long way to explaining why Scott Morrison started screaming hysterically about tax as soon as someone mentioned carbon at the #NPC last week. EU to hit Australia with a border tax on carbon emissions. thenewdaily.com.au/finance/2…
